Water‐switchable charge transfer : The microporous hydrated phase {[Fe(Tp)(CN) 3 ] 2 Co(bpe)} ⋅ 5 H 2 O shows spin transition induced by metal‐to‐metal charge transfer (MMCT), but no MMCT is observed in the corresponding dehydrated phase (see picture). Charge transfer can be reversibly switched through de‐ and rehydration. Tp=hydrotris(pyrazolyl)borate, bpe=1,2‐bis(4‐pyridyl)ethane. Fe green, Co orange, N blue, O red, C gray, B dark yellow.
